Title: Stroboscope speed indicator for record player turntables - is for different mains frequencies and at a standard speed generates patterns that are coincident
Inventor: ANTON KLAUS
IPC: G11B23/42
Filed: 1975-02-07
Abstract: A stroboscope disc is used to provide a ready means of monitoring the speed of record player turntables and to provide a means of accurate adjustment for different mains frequencies.

Title: DC coupling for A.C. systems of dissimilar frequency - is fitted with DC poles connected to earth through RC circuits
Inventor: EMELYANOW WIKTOR IWANOWITSCH
IPC: H02J3/36
Filed: 1975-11-27
Abstract: The object is to minimise the risk of heavy fault currents and high voltage peaks on the power components in a circuit coupling two a.c. power systems of dissimilar frequency. Rectifier (5) and inverter (6) are in a d.c. loop (7) and are connected to their respective a.c. systems (1, 2) through appropriate rectifier transformers (3, 4). The poles of the d.c. circuit are indirectly connected to earth (9) through RC elements (10), typically arranged symmetrically with respect to the poles. As there is no direct earth connection a single breakdown in insulation does not give rise to heavy fault currents, and the RC elements also act as voltage surge suppressors. The chances of a double earth fault on opposite poles is considered so extremely remote that it can be ignored.

Title: Harmonizing method for optoelectronic instruments - enables individual units to be plugged into instrument system
Inventor: SIEBECKER HANS DIPL ING DR
IPC: F41G3/32
Filed: 1976-06-04
Abstract: Automatic harmonising system is for several opto-electronic instruments operating in different wavebands. A test mark projector (7) operating in al the wavebands is fixed inside one of the instruments and a goniometer (3) is fixed inside one of the others. The goniometer produces electrical signals representing the deviation of a point target from its optical axis' (2). Optical element in the projector beam path (20) and the beam path (21) of an photodetector (6) use the signals from the goniometer to displace the projector test mark and the screen image so that the test point is imaged at the intersection of the goniometer axis (10) and the goniometer focal plane. The goniometer indicates zero deviation with its axis, which acts as a reference axis for all the other instruments.

Inventor: PAULL PETER LEONARD
IPC: C10J3/46
Filed: 1976-07-10
Abstract: Synthesis or fuel gas mixts. (constituents CO, CO2, H2, H2O, CH4, H2S, COS, N2, A) are produced by (a) mixing liquid CO2 and a solid particulate carbonaceous fuel at between -69 and +80 degrees F and at a pressure between above the triple point pressure of the CO2 and 1000 psig to produce an H2O-free slurry, (b) introducing the slurry at between-69 and + 1200 degrees F and at 76-4500 psia simultaneously with an O2-contg. (>21 mole % O2) gas at 80-500 degrees F and 76-4500 psia into a free-flow noncatalytic gas generator and (c) carrying out partial oxidation of the mixt. at an autogenous temp. of 1200-3000 degrees F and 30-4400 psia. The liquid CO2 serves both as slurrying agent and temp. moderator. The process utilises low cost high-sulphur solid fuel feeds, reduces heat load and consequently oxygen requirements of the gas generator, eliminates heat exchanger fouling, avoids excessive duty and temp. degradation of recoverable heat when using a waste heat boiler, and reduces single-pass carbon waste.
